Hot chocolate by the fire. Christmas carols. Stolen kisses in the snow. When Gwen's boyfriend Evan invites her to spend Christmas with his family, she pictures a perfect Hallmark Christmas scene, complete with all of the happy sighs and swoons.
But between Evan's brother who schedules the family's every move, his sister who's never met a mirror she didn't like, and the amorous newlyweds who flaunt their sexcapades, Gwen finds herself dodging the Perrys like it's her job. The more Evan's family brings their own brand of chaos to Christmas, the more Gwen wonders if she's in over her head, and if the Christmas of her dreams is going to turn into a real nightmare.
